The essential guide to caravan tyres

Your caravan’s tyres are its only point of contact with the road when travelling, making them a critical safety component. Unlike car tyres, caravan tyres often endure long periods of inactivity, carry heavy loads, and may require special attention to ensure they remain roadworthy. Proper maintenance and timely replacement are essential for safe towing.

In this guide, we’ll cover essential tyre safety tips, maintenance advice, and the official replacement recommendations from both major UK caravanning clubs.

Caravan Tyre Safety: Why It Matters

Caravan tyres are exposed to unique stresses, making them more prone to failure than regular car tyres. A sudden tyre blowout at speed can lead to dangerous situations, including loss of control and damage to your caravan. Ensuring your tyres are in optimal condition reduces these risks and provides peace of mind during your travels.

When Should You Replace Your Caravan Tyres?

The Caravan and Motorhome Club and The Camping and Caravanning Club offer clear guidance on tyre replacement. Both advise that caravan tyres should be changed every 5 years, regardless of tread depth, due to potential degradation. A further recommendation suggests that tyres should not be used after 7 years.

From a legal standpoint, it’s worth noting that the 5 to 7-year advice isn’t law. It is, however, based on very sound reasoning and years of experience. For example, the tyres on my mother-in-law’s caravan began to perish just weeks before their fifth birthday.

How old are the tyres on my caravan?

To determine your tyre’s age, check the DOT code on the sidewall. The last four digits represent the week and year of manufacture (e.g., “1220” means the tyre was made in the 12th week of 2020).

It’s worth noting that, provided the tyres are correctly stored, the 5 to 7-year guidance can begin from the fitment date, not the date of manufacture. If no fitment date is evident on a secondhand caravan, the date of manufacture can be used.

What is the DOT Code?

The DOT (Department of Transportation) code is a unique identifier found on the sidewall of your tyre. It provides important information about the tyre’s manufacturer, batch number, and, most importantly, age.

Caravan Tyre Maintenance: Key Checks and Best Practices

To maximise the lifespan and safety of your tyres, follow these maintenance tips:

1. Regular Pressure Checks

Maintaining the correct tyre pressure is essential for safe towing. Underinflated tyres increase rolling resistance, leading to overheating and potential blowouts. Overinflated tyres can, at best, cause poor traction and uneven wear.

  • Always check tyre pressures before every journey.
  • Refer to your caravan manual or data sticker (usually on the side of the caravan) for the correct pressures.
  • Use a high-quality tyre pressure gauge for accuracy.

2. Inspect for Cracks, Bulges, and Wear

Caravan tyres can develop cracks due to UV exposure and ageing. Perform a visual inspection regularly and look for the following:

  • Sidewall cracks or bulges to both sides.
  • Cracks within the tread.
  • Uneven wear patterns.
  • Embedded objects or cuts.

If you notice any damage, replace the tyre.

Check your caravan tyres regularly

3. Avoid Flat Spotting

Extended storage periods can cause flat-spotting. To prevent this:

  • Move your caravan slightly every so often.
  • Use tyre savers, which are shaped to fit the tyre.

4. Protecting Against UV Damage

Ultraviolet (UV) rays from sunlight can degrade tyres over time, leading to cracking. To protect against UV damage:

  • Park your caravan in a shaded area when possible.
  • Use caravan tyre covers, which shield tyres from direct sunlight and help extend their lifespan.

5. Store Your Caravan Properly

If you store your caravan for long periods:

  • Keep tyres out of direct sunlight to prevent UV degradation.
  • If a shaded spot isn’t available, consider using caravan tyre covers.
  • Inflate tyres to their recommended pressure even when in storage.

Choosing the Right Caravan Tyres

Selecting the correct tyres is essential for safety, performance, and longevity. Here are key factors to consider:

  • Load Rating.
  • Reinforced tyres.
  • Ply Ratings – 6-ply, 8-ply, etc.

The load rating of your tyre will depend on the caravan’s weight. Many variables exist here, such as a twin-axle caravan tyre supporting less weight than a single-axle caravan tyre, so consult your handbook. 

If there’s any doubt, the technical departments at The Caravan and Motorhome Club and The Camping and Caravanning Club will be able to help. For example, I needed a pair of unusually sized tyres for a 1960s caravan, and Martin from The Caravan and Motorhome Club dispensed invaluable advice. I now have a pair of tyres that perform flawlessly.

Fit the correct caravan tyre

1. Speed Ratings

Although caravans are typically towed at lower speeds, the speed rating is another important consideration.

  • Most caravan tyres are rated “N” (87 mph) or “R” (106 mph), both of which are more than adequate for UK speed limits.
  • Never fit tyres with a lower speed rating than originally specified by the manufacturer.

2. Avoid Part-Worn or Budget Tyres

It’s strongly recommended to avoid second-hand or low-quality budget tyres.

  • Part-worn tyres may have hidden damage or an unknown age.
  • Investing in premium tyres from reputable brands gives greater peace of mind.

Caravan Spare Wheels

A roadworthy spare wheel is essential for dealing with unexpected punctures or blowouts. When maintaining your spare wheel, ensure that:

  • The tyre is properly inflated and in good condition.
  • You have the necessary tools (jack, wheel brace, and torque wrench) to change a wheel if needed.
  • Does your breakdown cover include caravan tyre assistance?

If your caravan’s spare wheel is stored in a cradle under the caravan, take extra care to ensure the cradle is in good condition. Over time, cradles can become seized with rust, making removing the spare wheel in an emergency difficult. To prevent this:

  • Regularly inspect and lubricate the cradle mechanism.
  • Ensure the securing bolts or fasteners are not corroded.
  • Try lowering and raising the cradle periodically to confirm it is free-moving.
  • If the cradle is excessively rusted, consider replacing it before it becomes a serious issue.

Final Thoughts

Proper caravan tyre maintenance and timely replacement are crucial for safe and enjoyable travels. Following the 5-year and 7-year replacement guidelines, maintaining correct pressure, and conducting regular inspections will keep your tyres roadworthy.

Frequently Asked Questions (FAQs)

How often should I check my caravan tyre pressure?

You should check your caravan tyre pressure before every trip to ensure it is within the manufacturer’s recommended range. Check the tyre pressures when it’s in storage, too.

Can I use car tyres on my caravan?

Caravan tyres need to handle different loads and stresses. Always use tyres with the correct load rating and ply rating, as recommended by the caravan manufacturer.

How do I prevent my tyres from cracking?

Protect tyres from UV exposure with covers, or store your caravan in the shade.

Is a spare wheel essential for a caravan?

A spare wheel ensures you are prepared for punctures while travelling.

How can I tell if my caravan tyres are too old?

Check the DOT code on the tyre sidewall—the last four digits indicate the week and year of manufacture. Replace tyres every 5-7 years.
